This cosmic neighbor, located around 44 million light-years from us, is a relatively bulky example of a dwarf galaxy. Seen by the Hubble Space Telescope, this loosely-bound spiral galaxy is a perfect target for astronomers to study the puzzling aspects of dwarf galaxies. Find out more: http://go.nasa.gov/2fBq4TH

Joined a series of high level meetings to review the flood situation in various parts of the Northeast. Met CMs, Ministers and top officials from Arunachal Pradesh, Assam, Manipur and Nagaland.

A package of Rs. 2000 crore for flood relief, rehabilitation, reconstruction measures for affected states of the Northeast was announced. The package will have a significant component devoted to infrastructure & improving water holding capacity of the Brahmaputra.
